I think Kim Jong-Un emotes too much – in the posted photos he’s clearly Going Places and Doing Things, and possibly even having fun, and that’s why it doesn’t work.

By contrast, Kim Jong-Il is a tired old man slowly shuffling past an endless, surreal sequence of objects; in every photo his expression could be captioned “Oh god, another one.” I think there’s a bit of sympathy for this world-famous super-villain caught in a weird hell of his own devising, and that’s what makes it interesting.
